(But this should be preceded by conda update -n base conda or simply conda update conda so you have the latest conda version installed) In most cases what you want to do when you say that you want to update Anaconda is to execute the command: conda update -all You can deactivate your environment at any time by using the command conda deactivate on macOS, or simply deactivate on Windows.Root is the old (pre-conda 4.4) name for the main environment after conda 4.4, it was renamed to be base.

If you have made it to here, congratulations! Your Anaconda environment is all set up, as well as your virtual environment for the first lab. The output should be something similar to: tensor(, You can verify that Pytorch was installed correctly by opening a python session and entering the following: import torch By default, conda only searches the anaconda channel, where packages are released by default. The -c argument here tells conda what 'channel' it can find the package in. We also want to install Pytorch, but because Pytorch is distributed separately to most Anaconda packages, the command is slightly different:Ĭonda install -c pytorch pytorch torchvision Again, it may ask for your confirmation before installing any packages you don't already have. You can enumerate as many package names as you like after the install keyword and conda will install them all at once. Next, let's install some basic tools:Ĭonda install numpy jupyter pip matplotlib This confirms that we are now in the enviroment we just created, and that anything we install into Python here will stay within this sandbox. In your prompt, you should now see the name of the enviroment in brackets before the prompt line, like so: (Lab1) ➜ ~ Once the setup is done, you can activate the conda environment you just created by typing conda activate Lab1 on macOS, or simply activate Lab1 on Windows. The python=3.7 parameter is optional, but tells conda that this virtual environment requires Python (obviously) and that its version should be 3.4.x - this is important so that we are all working with the same version of Python.Ĭonda may install some packages here, which it will ask you to confirm before doing so. We can then create a new virtual environment with the following command:Īs you might expect, the -name parameter tells conda that the next phrase should be the name of this virtual environment. To set up your first virtual environment, open the Terminal on macOS or the Anaconda Prompt on Windows. This is extremely useful when you are working on multiple Python projects at once - instead of having one messy installation with every package imagineable downloaded, virtual environments ensure that each project has its own tidy playground with only the tools it requires. Virtual environments are a powerful tool which allows us to maintain multiple distinct Python installations. message here - that confirms you are now using Anaconda Python. The critical part is to verify that you see the Anaconda, Inc. Type 'help', 'copyright', 'credits' or 'license' for more information. You should see a message like this one: Python 3.7.3 (default, Mar 27 2019, 16:54:48) Upon doing so, verify that Anaconda installed correctly by typing python into the terminal. Once the installation is complete, you need to quit and then re-open the Terminal application. bashrc' - I highly recommend you enter 'yes' here unless you have a specific reason to use your existing Python installation. Once it's complete, the installer will ask you whether you want to 'add anaconda to. The installation itself can take quite some time, so be patient. You will have to agree to the terms of service, and answer some configuration options, all of which you can leave at the default setting. Now, to install, enter the command bash Anaconda3-2019.03-MacOSX-x86_64.sh which will tell your mac to run the file as an executable (note: for long file names like this one, you can enter part of the name and then hit the tab key for the terminal to autocomplete). If you see No such file or directory then you have either downloaded the file to a different directory, not downloaded the correct file, or named it differently when downloading. Open the Terminal application on your mac and navigate to the downloads folder like so: cd Downloads ( cd stands for change disk, and is the command for navigating between folders in almost every contemporary operating system.) From here, you can confirm that the file has been downloaded correctly by entering the command ls Anaconda3-2019.03-MacOSX-x86_64.sh.
